Abstract: 918,628. Cam-operated switches. RAYDEX Ltd. Jan. 9, 1961 [Jan. 7, 1960], No. 567/60. Class 38 (5). A switch operated by successive pulls on a flexible member 11 comprises body parts 4 and 7 riveted together to house a contact actuator 17 and a resilient leaf-spring reciprocable member 10 which has a tongue 21 to rotate actuator 17 through 90 degrees each time cord 11 is operated. Actuator 17 has a part 18 of square crosssection, cylindrical bearing portions 19 and a flat cam 20 on each end to move bridging contacts 22 alternately into and out of engagement with respective pairs of fixed contacts 5, carried on body part 4. The restoring spring 14 acts between a collar 15, sitting on shoulders 16 (Fig. 2), and a loose collar 13 engaged by lugs 12 on member 10. Collar 13 has a central feeler 26 which enters a hole 27 in actuator 17 in one position thereof (Fig. 1) but is obstructed in the other rest position thereof (Fig. 4, not shown) such that the member 10 does not fully restore in the latter case even though cord 11 has been released. An indicator plate 24 has a part mounted between spring 14 and collar 13 and a perpendicular portion which is partly visible through a window 25 in body part 4 and thereby indicates the condition of actuator 17. The plate 24 may have a second perpendicular portion visible through a corresponding window in body part 7. Specification 918,627 is referred to.

Title: Improvements in or relating to phonographs
Filed: 1929-01-07
Abstract: 304,191. Dictaphone Corporation, (Assignees of Johnson, A. A.). Jan. 16, 1928, [Convention date]. Feed mechanism; returning sound-box to intermediate point.-The carriage-driving mechanism of dictation machines is constantly in gear but permits lateral adjustment, and mechanism is provided for effecting back and forward spac. ing and for holding the stylus against free movement during such spacing. The carriage 14 guided on ba,rs 12, 13 carries a worm-wheel 34 constantly gearing with the usual feed screw 29 driven by gearing 30 from the mandrel shaft 17, and the wheel 34 is frictionally held by a resilient spider 38 and adjusting nut 40 so as to transmit the normal traverse whilst permitting forcible lateral traverse by the wheel rolling along the screw. Back and forward spacing respectively is effected by levers 44, 64 mounted on a sleeve 45 on the guide 12, and which on depression against the action of a spring 48 arranged in the bosses 49 of the levers brings one or other of the pawls 47, 65 into engagement, with a fixed rack 51 to slide the carriage for a small distance, the wheel 34 rolling along the screw 29. Depression of either lever first clamps the stylus-carrying bracket 24 against lateral movement so that the stylus rides over the grooves in the record during adjustment of the carriage. This clamping is effected, when the lever 44 is depressed, by a lug 63 thereon rocking a spindle 60 so that a lug 59 acts through a spring 57 and pivoted lever 56 to apply a clamping plate 52 carried by the sound-box against a clamping plate 53 carried by the stylus bracket 24. Depression of the lever 64 acts through a lug 68, arm 67, and the lever 56 to effect the clamping action. Reference has been directed by the Comptroller to Specification 15861/12.

Title: Moisture-impervious package of impression material and method of preparing the same
IPC: B65D81/00
Filed: 1938-01-10
Abstract: 500,000. Capsules; packages of hydrocolloid impression material. TRIGGS, W. W. (Surgident, Ltd.) Jan. 10, 1938, No. 706. [Class 81 (i)] [Also in Group XVII] Packages of moisturecontaining hydrocolloid dental impression compositions of the kind described in Specifications 271,306, [Class 70], and 464,978, [Group V], are prepared by forming an elongated body of said composition having a partial coating of a flexible moisture-impervious material and then applying a fluid coating composition to the remaining surface so as to overlap and become bonded to the first mentioned coating. The coating composition should be such as to permit the unopened package to be moderately heated to render the hvdrocolloid fluent and to be flexible so as to permit the package to be kneaded whilst cooling to body temperature. Suitable coating materials are vinyl resins such as the polymerized vinyl halide resin known as Koroseal, or a solution thereof known as Korolac, or mixed solutions of cellulosic compounds with moisture-proofing substances such as rubber, resins, resinous gums or waxes. A rod of hydrocolloid 2, Fig. 2, may be extruded into a bath of coating composition to form a coating 1, cut into lengths and coated at the ends 3 by dipping ; or lengths of uncoated hydrocolloid may be dipped for part of their length and then dipped at their other ends so that the coatings formed overlap ; or the hydrocolloid may be cast into a pre-formed capsule 8, Fig. 5, and the open end dipped to form a sealing cap 10. In the first of these methods the coating 1 may be formed by anodic deposition from a latex dispersion, or the extruded rod of composition may be coated by a series of spraying operations alternating with treatment by hot air blasts. An example of a liquid for coating by dipping is a mixture of solutions of celluloid and of rubber respectively, in cyclohexanol or its acetate. Celluloid alone is stated to be unsuitable as a coating composition. Specification 444,908 also is referred to.

Abstract: 1,070,401. Inductive control systems. ELECTRONIC & AUTOMATION ENGINEERS Ltd. Dec. 29, 1964 [Jan. 9, 1964], No. 993/64. Heading H4U. In an inductive control system a transmitting coil is energized by an associated alteiiiating current generator so that when it is in the proximity of either of two receiving coils, which are connected in series or in parallel, a signal, which may be modulated or pulsed, is induced therein and operates a relay. Either the transmitting equipment is mounted on mobile means and the receiving equipment is fixed, or vice versa. As described, a vehicle carries a generator operating on a selected fixed frequency in the range 8-25 kc/s. and has a transmitting coil mounted underneath. One receiving coil is placed on or under the ground outside the doors of a garage, and the other is similarly placed inside. A tuned receiver connected to the receiving coils operates a relay controlling a power supply to apparatus for actuating the doors. In this way, the doors may be made to open as the vehicle approaches the garage, and to close after it has entered.
Patent HK-24888-A (HK)
Title: Electronic timepiece
Inventor: BESSON RENE
IPC: G04G3/02
Filed: 1988-04-07
Abstract: An electronic watch comprises a stepping motor 6 for driving a mechanism for displaying the time information, a quartz crystal controlled oscillator 1, a frequency divider 2 with an adjustable division ratio, a circuit 7 for adjusting the division ratio eg by suppressing a number of pulses from the oscillator to the divider, a memory 8 containing data corresponding to the number of the pulses to be suppressed in each adjusting, cycle and a logic circuit 10 which, in response to an interrogation signal, (switch 9) produces a measuring signal at the output of gate 19 which is supplied to the coil of the stepping motor and which comprises a series of pulse trains whose distribution is representative of the division factor and the frequency of the oscillator and whose duration is sufficiently short so as not to cause the motor to rotate and sufficiently long to cause a magnetic stray field from the motor which can be detected by an external apparatus for measuring therefrom the rate of the watch. The interrogation signal upon closure of switch 9 causes the divider to divide with its unadjusted value. A gate 11 is enabled by 1 Hz pulses at 11a to pass trains of 256 Hz pulses in alternate half quartz-second intervals. The pulses pass through the gate 19 until their number, counted by counter 17, equals the adjustment number eg 5 held in memory 8. The interrogation signal also acts on switch circuit 4 to disconnect the motor control inputs at 4a 4b of circuit 5 from the divider 2, and apply the measuring signal pulses at input 4e from the gate 19 instead. In the embodiment described, a "quartz-second" is shorter than a normal second, the watch crystal frequency being higher than a nominal frequency, alternatively the measuring signal may be transmitted acoustically. The external measuring apparatus is described in App No. 79/36415. <IMAGE>
